From St. Moritz via Hamburg to the Nürburgring Nordschleife
September 2022 was a very special month for our company, Cropfiber GmbH, and its ASPHALTKIND brand!
Right at the start of the month, we celebrated the official launch of our ASPHALTKIND roof boxwith a trip to St. Moritz for the Kilomètre Lancé, the “Top International Sprint for Record-Breaking Vehicles.”
After that, we made a brief stop along the beautiful mountain switchbacks near Munich, Ingolstadt, and the surrounding area, then headed toward Hamburg! There, we visited a few hotspots for photos and showcased the aerodynamic roof box to curious onlookers.
Driving the Nürburgring Nordschleife with a roof box
Driving on the legendary track in the Eifel is a must for all automakers, including BMW, Audi, Porsche, Mercedes, and now Tesla as well. So it’s exactly the right setting for our ASPHALTKIND roof box! Amid prototype cars, tourist drives, and track day enthusiasts, we hit the Ring under ideal conditions. Our goal: to prove that our roof box is suitable for high speeds.
Our race car driver, equipped with a helmet and racing suit and who knows the track inside and out, didn't go easy on the equipment. Both the car and the roof box were subjected to significant lateral and longitudinal dynamic forces that cannot be experienced in normal traffic conditions.
The 8:20-minute lap time recorded using the Sport Chrono Package and the pretty worn-out sidewalls of the street tires underscore the (cornering) speeds that were achieved. Of course, this didn’t go unnoticed by the spectators and photographers at the Brünnchen, the Schwalbenschwanz, and the Caracciola Carousel, and in addition to photos, we received a lot of positive feedback and had plenty to talk about!

More InformationWe can only answer the most frequently asked question—“How fast can you drive with a roof box?”—to a limited extent. The cornering speeds were just barely below the point where we’d end up in the guardrail. The deceleration figures—that is, braking from high speeds into tight corners—were impressive and exactly the right kind of terrain for the powerful brakes. So, it’s the perfect roof box for a sports car, like a Porsche 911!
True to our motto:“Developed and tested on a sports car. Built for station wagons, sedans, SUVs, and coupes—as well as the left lane,” we can now proudly announce: The ASPHALTKIND “Cropfiber” roof box is Approved by Nordschleife. And by the curious glances in St. Moritz and Hamburg. Our goal at the start of developing the best roof box on the market was to ensure that the
We focused on aerodynamics, stability, weight, and design. We are now proud to announce that we have achieved this. With our Performance roof box, you can reach top speeds: in any case, you can drive faster than 130 km/h with the roof box.
That is exactly what has now convinced a group of customers for whom we have been manufacturing customized roof boxes according to their specifications at our in-house production facility in Dortmund for the past few weeks.
There are still a few production slots available for prompt delivery. So don't wait too long—be as fast as the 911 with a roof box and place your order now!
